ABSTRACT:
A device for applying liquid agents by synthetic bristles which, combined into bundles, are fixed on a plastic supporting base, with the supporting base being thin-walled and having several openings at least one of which is surrounded by a bundle of bristles. The bristles are butt-welded onto the supporting base, with the bristles leaving open a cross section of the opening and forming a duct tapering off toward the bristle ends, which duct leads or supplies the agent into a working area of the device.
